A simple library providing functionality to generate a 'device ID' that can be used to uniquely identify a computer.

Hi, I'm Matthew King, a software engineer from Perth, Western Australia.

I build all sorts of software. I'm passionate about C# and .NET, and like to work with cutting-edge technology. I sometimes blog about software development, and I have a few open source projects that you might find interesting.

Here are some relevant links:

deviceid's Issues

Could not load file or assembly 'System.Management

i run this code on my asp.net core website and its working even published to iis
string mbInfo = new DeviceIdBuilder() .OnWindows(x => { x.AddMotherboardSerialNumber(); }) .ToString() .Substring(0,7);
but on windows server in iis gives me shuch a log

  System.IO.FileNotFoundException: Could not load file or assembly 'System.Management, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

System.PlatformNotSupportedException on Win Server 2012

Hi, I write a .net5 app that try to get the machine id. The code is simple:

public string GetId() => new DeviceIdBuilder()
                                .AddProcessorId()
                                .AddMacAddress(true, true)
                                .ToString();

It works fine on win 10, but on a win server 2012 I get this error: System.PlatformNotSupportedException: The native library 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\wminet_utils.dll' does not have all required functions. Please, update the .NET Framework.

I then install the .net framework 4.8 , but it doesn't help.

feature : Unique Device & App Installation Identifiers for Mobile Apps

Hello,

It will be nice to add xamarin device id like this:
https://montemagno.com/unique-device-id-for-mobile-apps/

DeviceId changed every time after reboot

I'm using new DeviceIdBuilder().AddMacAddress().AddMotherboardSerialNumber().ToString() to identify a unique computer.
But it always changing after a reboot. Am I using it right ?

DeviceId doesn't work in docker for Windows containers.

Hello,

we use DeviceId in docker. It works in a Linux container, but not in a Windows container.
You support AddDockerContainerId for DeviceId.Linux in the README file. Do you also support Windows containers?

I found the problem where it fails is on this line:

DeviceId/src/DeviceId.Windows.Wmi/Components/WmiSystemDriveSerialNumberDeviceIdComponent.cs

Line 23 in 6be01e1

var systemLogicalDiskDeviceId = Environment.GetFolderPath(Environment.SpecialFolder.System).Substring(0, 2);

Environment.SpecialFolder.System returns "System"
Environment.GetFolderPath(Environment.SpecialFolder.System) returns an empty string so Substring(0, 2) fails.

Failure with this code:

string deviceId = new DeviceIdBuilder()
    .OnWindows(windows => windows
        .AddProcessorId()
        .AddMotherboardSerialNumber()
        .AddSystemDriveSerialNumber()
        .AddSystemUuid())
    .OnLinux(linux => linux
        .AddCpuInfo()
        .AddMotherboardSerialNumber()
        .AddSystemDriveSerialNumber()
        .AddMachineId())
    .AddFileToken(TokenFilePath)
    .AddMachineName()
    .ToString();

Line 22 in 9c81245

var systemLogicalDiskDeviceId = Environment.GetFolderPath(Environment.SpecialFolder.System).Substring(0, 2);

Thank you in advance for your feedback.

After Update nothing works.

After 6.0.0 update you change much, readme is outdated.
.AddProcessorId.. does not exist anymore.

What you change?

Version compatible

Hi,
I am using version 5.2 for generating DeviceID as follows:
string deviceId = new DeviceIdBuilder()
.AddMachineName()
.AddProcessorId()
.AddMotherboardSerialNumber()
.ToString();

I noted that on version 6.2 the "same" instructions generate a different result:
string deviceId = new DeviceIdBuilder()
.AddMachineName()
.OnWindows(windows => windows.AddProcessorId().AddMotherboardSerialNumber())
.ToString();

Is possible to generated a device ID which is back-compatible with version 5.2?

Thanks in advance

Device ID is not unique and changing over time

Hi, thank you for the package. I am facing an issue, I am generating the IDs in a "service worker" in Windows Service mode using the below command. I am using the base package DeviceId without any other extension packages.

 new DeviceIdBuilder()
        .AddUserName()
        .AddMachineName()
        .AddMacAddress(excludeWireless: true)
        .ToString();

It works great but in a span of few hours (on the same network & machine) the generated ID gets changed.

Isn't "Mac Address" is used as a seed to generate random string? Shouldn't that be unique always?

AddOSInstallationID() returns 'null' as value in Windows running as 32bit

Hi, when calling AddOSInstallationID() in a process running as 32bit on Windows its value will be 'null' instead of the actual GUID.

Why generates different DeviceId's on different applications on same device?

I'm generating device id as: new DeviceIdBuilder().AddMachineName().AddMacAddress().AddOsVersion().ToString();

I expect it generates same device id on same device even for different apps.

This statement generates DeviceId1 on App1 on Device1, however DeviceId2 on App2 (different app) on Device1 (same device).

I'm not including any app information in this statement, so app shouldn't matter if it's same device.

The things I include are:

MachineName: same
MacAddress: same
OsVersion: same

Dockersupport

If the application runs in a docker container some functions won't work:

• AddMotherboardSerialNumber() aka/sys/class/dmi/id/board_serial won't work as the file doesn't exit
• AddSystemUUID() aka /sys/class/dmi/id/product_uuid won't work as the file doesn't exit

Maybe: head -1 /proc/self/cgroup|cut -d/ -f3 could help out with one of them.

Docker0 bridge interface is including to macaddress

Docker is creating bridge interface in system with name docker0. DeviceId is including macaddress of this interface and it's fine but docker0 interface got new macaddress after PC reboot so we got new device id.

.NET Standard with Nuget package

Could it be that the .NET standard version is missing some code? I just added deviceId 4.0 to y .NET standard 2.0 project, and it seems the dll does not contain the DeviceIdBuilderExtensions, so calling any .AddXYZ() methods on the DeviceIdBuilder is not possible.

Migration to v6

Hello, I recently migrated your library to version 6.
With big disappointing I can't get the same result as version 5.
This is my code:

// old code
         string deviceIdV5 = new DeviceIdBuilder()
               .AddSystemUUID()
               .AddProcessorId()
               .AddMotherboardSerialNumber()
               .AddSystemDriveSerialNumber()
               .ToString();

// new code
            string deviceIdV6 = new DeviceIdBuilder()
                .OnWindows(w => w
                    .AddSystemUuid()
                    .AddProcessorId()
                    .AddMotherboardSerialNumber()
                    .AddSystemDriveSerialNumber()
                    )
                .OnLinux(l => l
                    .AddCpuInfo()
                    .AddMachineId()
                    .AddProductUuid()
                    .AddMotherboardSerialNumber()
                    .AddSystemDriveSerialNumber()
                    )
                .ToString();

Is there a way to get the new code generate the same value as the old one?

DeviceIdBuilder AddSystemDriveSerialNumber() - System.Management.ManagementException: Invalid class

Hi

We're seeing an issue on some users machines (few and far in between, but regular enough to be a problem). It seems that using the AddSystemDriveSerialNumber() method for DeviceIdBuilder is causing an exception to be thrown on these machines (stack trace below). We are currently still using 5.2.0 primarily due to the WMI vs MMI issue, so I would expect to receive the same issue on the newer 6.x versions using WMI as I can't see that anything was changed in this area.

System.Management.ManagementException: Invalid class 
   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
   at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()
   at DeviceId.Components.SystemDriveSerialNumberDeviceIdComponent.GetValue()

   at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source)
   at DeviceId.Formatters.HashDeviceIdFormatter.GetDeviceId(IEnumerable`1 components)
   at DeviceId.DeviceIdBuilder.ToString()

As this is only happening on some machines, and we don't have direct access to any of them I can't provide any code to reproduce this. I'm hoping that you may have some idea as to why this may happen and how we can work around the issue?

Thanks

Processor Id vs SerialNumber

Firstly, thank you for this awesome project

Just some questions:

1. Why do you use ProcessorId instead of SerialNumber? I guess compatibility because it looks SerialNumber "is not supported before Windows Server 2016 and Windows 10";
2. At least for me, appears ProcessorId is something to identify a cpu model, it does not look unique enough... EDIT: I tested 2 computers with the same processor model, and the ProcessorId returned is the same... so my theory is correct. Maybe something to explain in readme.md file?
3. Do you plan expose this Processor SerialNumber in future?

My reference for these informations is here.

Incompatible when used with .NET 5 in SingleFile option

I have a sample WPF project running on .NET 5. Everything works fine for both debug and release environments. However, if I publish the project with target runtime as win-x64 or win-x86 with "Produce Single File" option, the following error occurs.

This error is logged with Serilog

NET8.0 DeviceId.Windows.Mmi not working

Hi,
Recently i was migrating one of my projects to NET8 RC2.
Noted that DeviceId.Windows.Mmi throws an error.

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Management.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Management.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

   at DeviceId.Windows.Mmi.Components.MmiWqlDeviceIdComponent.GetValue()

the package which throws the error is included inside DeviceId.Windows.Mmi

by removing MMI reference, at least for windows (11) all seems to work.

The error occurs only on runtime, but compiles fine.
Inside build folder there are files like:
DeviceId.*.dll
but no explicitly the dll that throws the error althought i assume its included in DeviceId.Windows.Mmi.dll

here is my configuration:

//excluding wireless and non physical becouse they might change MAC more easily
var deviceIdBuilder = new DeviceIdBuilder()
    .AddOsVersion()
    .OnWindows(windows => windows
        .AddMachineGuid()
        .AddWindowsDeviceId()
        .AddWindowsProductId()
        //mmi stopped working in NET8.0
        //.AddMacAddressFromMmi(excludeWireless: true, excludeNonPhysical: true)
        //.AddSystemUuid()
        )
    .OnLinux(linux => linux
        .AddProductUuid()
        .AddMotherboardSerialNumber()
        )
    .OnMac(mac => mac
        .AddPlatformSerialNumber()
        );

//Processor Id creates issues on linux as it may change (if programm is executing on different Processor from before)
//[Windows] -> AddSystemUuid seems not to be unique (at least in .NET)
var MachineId = deviceIdBuilder
    .UseFormatter(new HashDeviceIdFormatter(() =>
        SHA256.Create(),
        new Base64UrlByteArrayEncoder()
     ))
    .ToString();

Thanks in advance.

AddCpuInfo always return new id

Hi,

Method AddCpuInfo for linux is reading /proc/cpuinfo and using FileContentsDeviceIdComponent for getting cpu id.

First command run

Second command run

Please take a look at cpu MHz field, is changing depending on cpu usage.

Wrong ProcessorId and MotherboardSerialNumber

I'm getting "To be filled by O.E.M..BFEBFBFF000306A9" by executing:

var t = new DeviceIdBuilder().AddProcessorId().AddMotherboardSerialNumber().UseFormatter(new StringDeviceIdFormatter(new PlainTextDeviceIdComponentEncoder())).ToString();

I've tested the same code in other computer with the same result.

Here is my System Information, if its helps.

Use inheritance for specific DeviceIdBuilders

Hi,

I've noticed, that using general device ID features like the OS version can't be used device specific. This means, it is possible to call AddOsVersion not dependent on the system you are running on:

This works:

string deviceId = new DeviceIdBuilder()
    .AddMachineName()
    .AddOsVersion()
    .OnWindows(windows => windows
        .AddProcessorId())
    .OnLinux(linux => linux
        .AddCpuInfo())
    .ToString();

This works not:

string deviceId = new DeviceIdBuilder()
    .AddMachineName()
    .OnWindows(windows => windows
        .AddProcessorId())
    .OnLinux(linux => linux
        .AddOsVersion()
        .AddCpuInfo())
    .ToString();

The reason seems to be some type specific handling here. From my point of view, this could be solved by changing the way to create the specific builders to inheritance.

If LinuxDeviceIdBuilder inherits from DeviceIdBuilder, overriding the corresponding methods, this would solve the problem. As an alternative the base builder property could be made public. Is there a reason why this is not done like this? If not, I could create a PR with the proposed changes. Let me know what you think about it.

[Question] DeviceId 6.3 nuget release dates?

Good afternoon @MatthewKing,
Is there any date for releasing the new version as a nuget package? It's still not available, only 6.2.
Thank you.

Trigger Nuget build

The last version is 4 months old, please update Nuget with the latest commits for OSX

Release documentation

Hi,
I tried to upgrade from 5.2.0 to 6.0.0.

Unfortunately the API changed and I don't know if this would affect my program, by returning different DeviceIds for the same machine/configuration or if I need to do some migration.

For example the AddOSInstallationID-method, that I use is gone.

It would be great if you document your releases and possibly breaking changes.

Question: Linux support and VM/AWS

Looks interesting! Does this support VM and AWS? Or plans for it? And Would this work in .NET Core (sorry, still new to C#).

Is OS installation ID a constant per machine?

Is it stays same when u install newer or reinstall same version of Windows/Linux on the same machine?
Asking because on OSX it is constant through the device lifetime

AddOSInstallationID

Hello
Returning different values for "AddOSInstallationID" method net5 and framework 4.7.2

Using package DeviceId.Wmi - MotherboardSerialNumber gives WPF scroll issues

For a full stack WPF application with multiple projects the DeviceId.Wmi library for some reason gives touch scroll issues when used.

Adding the library as Nuget package to my Infrastructure layer project would make my WPF UI layer project give touch scroll issues. The touch still works but the scrollviewer in particular could not easily be scrolled anymore (PanningMode is set to Both).

I have created a simple project where the issue is active: TestTouchScroll-issue.zip. If you comment the lines in the MainWindow.xaml.cs - line 15 to 18 the problem is fixed. So it has to do something with the .AddMotherboardSerialNumber() or .AddMachineGuid() method that is called. I also found out that removing the MotherboardSerialNumber method fixes the issue. (the MachineGuid method doesn't use the Wmi library, i suspect the problem to lie in the Wmi library).

Hopefully this information is useful enough and feel free to ask for more information if required! Thank you in advance! Great library never the less!

Cheers, Pepijn

IOS/Android

any support for IOS & Android devices?

Referenced assembly 'DeviceId' does not have a strong name

Referenced assembly 'DeviceId' does not have a strong name

Can you sign the package so it can be used in a project where all the assemblies are signed?

MacAddress changes

Related: #67
version: 6.4.0

I encountered an issue with AddMacAddress and setting the excludeWireless is not helping.

After installing Windows Updates the deviceId changed so I investigated a little bit.

The resulting devideId is changing in case of:

1. Windows Update (driver updates?)
2. Enable/Disable Bluetooth also changes the results even with excludeWireless: true

Is there a way to improve it so it will use the Mainboard NetworkAdapter or first LanAdapter found and return the Physical Address always?

Add support for .NET 5 (and later)

DeviceId targets .NETStandard 2.0, so in principle it should work on net5.0. Unfortunately, the project uses the obsolete platform abstraction package, which is not available for net5.0 (except for an old preview version). For that reason, it would be great to have a net5.0 target. Once #25 is merged, the net5.0 version would be identical to the netStandard version, except for the deprecated dependency.

See https://docs.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/5.0/platformabstractions-package-removed for details.

Device ID on docker container

Hi,
I have a question about docker container in particular running on azure.
I am using DeviceId library to have a unque ID for generating license for customer that want to use our company software.
I experienced that on any container creation (and it is also correct) the DeviceID changes and therefore license become invalid.
When running docker hosted in azure could be useful to get the Azure tenantId of the current running subscription.
In general I would like to have a unique ID when running docker even after having built a new container.

Any suggestion?
Thanks in advance

Validate the DeviceId is semantically correct

I am attempting to validate that a DeviceId provided via a web form is valid - but I do not have access to the machine that the deviceId would have been generated.

I am attempting to check that the device Id provided is correct in that it could have been generated on a machine - and isn't simply a jumble of characters typed into the textbox.

Aside from checking the length and looking for invalid characters (Is there a list?), is there anything I can do to check the semantic correctness of the string? Does the length vary?

Many thanks for any help and for creating this great software!

Mistake in migration guide?

The migration guide in the readme states that for AddOSInstallationID (on mac) the equivalent in v6+ should be AddSystemDriveSerialNumber but - looking at the v5 & v6 implementations I think the README should state the equivalent is actually AddPlatformSerialNumber.

AddOSInstallationID v5:

DeviceId/src/DeviceId/DeviceIdBuilderExtensions.cs

Lines 186 to 189 in fd2fb79

	return builder.AddComponent(new CommandComponent(
	name: "OSInstallationID",
	command: "ioreg -l | grep IOPlatformSerialNumber | sed 's/.*= //' | sed 's/\"//g'",
	commandExecutor: CommandExecutor.Bash));

AddPlatformSerialNumber v6:

DeviceId/src/DeviceId.Mac/MacDeviceIdBuilderExtensions.cs

return builder.AddComponent("IOPlatformSerialNumber", new CommandComponent("ioreg -l | grep IOPlatformSerialNumber | sed 's/.*= //' | sed 's/\"//g'", CommandExecutor.Bash));

The commands executed are identical between these two (and not in AddSystemDriveSerialNumber)

Permissions levels?

I am using v5.3 of the library (a bit old, but I haven't fully tested the new version).

I have the following for generating an unique id for each user:

if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
    try
    {
        return new DeviceIdBuilder()
            .AddProcessorId()
            .AddComponent(new CDriveSerialNumber())
            .ToString();
    }
    catch
    {
        return new DeviceIdBuilder()
            .AddProcessorId()
            .AddSystemDriveSerialNumber()
            .ToString();
    }
}

public class CDriveSerialNumber : IDeviceIdComponent
{
    public string Name { get; } = "CDriveSerialNumber";

    public string GetValue()
    {
        using (var mo = new ManagementObject("win32_logicaldisk.deviceid=\"C:\""))
        {
            return mo["VolumeSerialNumber"].ToString();
        }
    }
}

I have some exception telemetry set up and every once in a while, I saw the following:

System.UnauthorizedAccessException: Access is denied. (0x80070005 (E_ACCESSDENIED))
   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(Int32 errorCode, IntPtr errorInfo)
   at System.Management.ManagementScope.InitializeGuts(Object o)
   at System.Management.ManagementScope.Initialize()
   at System.Management.ManagementObject.Initialize(Boolean getObject)
   at System.Management.ManagementBaseObject.get_Properties()
   at System.Management.ManagementBaseObject.GetPropertyValue(String propertyName)
   at System.Management.ManagementBaseObject.get_Item(String propertyName)
   at Base.CDriveSerialNumber.GetValue()

So I added the try-catch with AddSystemDriveSerialNumber instead and definitely see this issue less often, but I still see a bit of:

Microsoft.Management.Infrastructure.CimException: Access is denied. 
  ?, in bool CimSyncEnumeratorBase<T>.MoveNext()
  ?, in string Wmi.GetSystemDriveSerialNumber()
  ?, in string SystemDriveSerialNumberDeviceIdComponent.GetValue()

Basically, what I'm asking is the following: what are the most stable id properties (least likely to change - like motherboard serial number as opposed to MAC address or OS Version) that also require the least permissions to access (for instance, I don't think I've ever seen an issue with my usage of AddProcessorId)?

Additionally, do you know of any resource that could rank all the component builders in DeviceId according to the permissions level required? I've been trying to find some resources online, but can't find anything

Convert String to Component

After creating a deviceId, how do you convert it back if you know the conponents of builder?
I am trying to create a client and server communication.

Downgrade the System.Management dependency to version 6 for .net standard 2.0

Hi all!

Can we consider downgrading the System.Management dependency to version 6 for .net standard 2.0 target of the DeviceId.Windows.Wmi package? It is currently dependent on version 7 which is incompatible with .net core 3.1 and .net 5 which are covered by the .net standard 2.0 umbrella.

Thanks a lot for all this incredible work, by the way!

JsonException when generating Id on Alpine Linux

Hello,
I am facing an issue generating a device id that happens only on Alpine Linux. The specific context is a docker container using the official dotnet/sdk:7.0-alpine image. On Windows and on my Ubuntu container everything runs fine.

The code used to generate the machine ID is this one:

new DeviceIdBuilder()
        .AddMacAddress(true)
        .OnWindows(windows => windows
            .AddProcessorId()
            .AddMotherboardSerialNumber()
            .AddSystemDriveSerialNumber())
        .OnLinux(linux => linux
            .AddCpuInfo()
            .AddMotherboardSerialNumber()
            .AddSystemDriveSerialNumber())
        .ToString()

And the error I'm getting is this one:

System.TypeInitializationException : The type initializer for 'XXX.Common.Utilities.Security.Device' threw an exception.
---- System.Text.Json.JsonException : The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. Path: $ | LineNumber: 0 | BytePositionInLine: 0.

I would appreciate any feedback even if it's that alpine linux is not supported. Thanks.

System.Management equivelants?

Previously, I've been using this to generate a unique ID (based on this SO answer):

public static string GetUniquePCIdentifier()
{
    string cpuInfo = string.Empty;
    ManagementClass mc = new ManagementClass("win32_processor");
    ManagementObjectCollection moc = mc.GetInstances();

    foreach (ManagementObject mo in moc)
    {
        cpuInfo = mo.Properties["processorID"].Value.ToString();
        break;
    }

    string drive = "C";
    ManagementObject dsk = new ManagementObject(
        @"win32_logicaldisk.deviceid=""" + drive + @":""");
    dsk.Get();
    string volumeSerial = dsk["VolumeSerialNumber"].ToString();

    return cpuInfo + volumeSerial;
}

Running that on my computer gives me the ID BFEBFBFF000306C34408F4F4.

I figured the equivalent in the DeviceId library would be something like:

public static string GetUniquePCIdentifier()
{
    return new DeviceIdBuilder().AddProcessorId().AddSystemDriveSerialNumber().ToString();
}

But that gives me the ID nS9mx7meCmiAvsfZpyTLK_aQtGkgPljmld7nl4po35A (which isn't anywhere close to what I had above). Does the DeviceId library use one of the hashing formatters by default?

If possible, I'd like to migrate to this library and still keep generating the same IDs as I was before. Am I using the library correctly or is this just not possible?

DeviceID returns different IDs?

Hello,

there is a problem with the library - maybe you can find out why the DeviceID returns different ID strings.

1. I used the library direct with NuGet package
2. I used the same function from my own library in COM Inteorp with Excel VBA

The strange thing is i get two different IDs from the library - but how i said its the same function.
Under this is my "Testcode" with the two different outputs.

In the end you can see i tried first the DeviceID library and after that i used directly the System.Management.
With the System.Management i get two times the same ID.

        string one = new DeviceIdBuilder().AddMachineName().ToString();
        string two = new DeviceIdBuilder().OnWindows(windows => windows.AddProcessorId()).ToString();
        string three = new DeviceIdBuilder().OnWindows(windows => windows.AddMotherboardSerialNumber()).ToString();
        string four = new DeviceIdBuilder().OnWindows(windows => windows.AddSystemSerialDriveNumber()).ToString();

        string uniqueID = new DeviceIdBuilder()
            .AddMachineName()
            .OnWindows(windows => windows
                .AddProcessorId()
                .AddMotherboardSerialNumber()
                .AddSystemSerialDriveNumber())
            //.OnLinux(linux => linux
            //    .AddMotherboardSerialNumber()
            //    .AddSystemDriveSerialNumber())
            //.OnMac(mac => mac
            //    .AddSystemDriveSerialNumber()
            //    .AddPlatformSerialNumber())
            .ToString();

        var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor");
        ManagementObjectCollection mbsList = mbs.Get();
        string id = "";
        foreach (ManagementObject mo in mbsList)
        {
            id = mo["ProcessorId"].ToString();
            break;
        }`

.AddProcessorId() disappeared in version 6

Hello,
I have some apps using your lib.
None works after upgrading to version 6 because .AddProcessorId() simply is no more present.

Can you fix it or tell me how to achieve the equivalent result?

Thank you.

How to get deviceId from Client ?

I want get deviceToken for each client requesting my site.

You want to depend on the machine, not the browser.

i tried user-agent but user-agent is depending browser and os, it is not unique.

Your library can provide deviceid of client?

i am run on windows xp sp3,it crashed

[feature] add a static method for simple and quick use

adding this static method:

DeviceId.FingerPrint(systemUUID: true, processorId: true, motherboardSN: true, hashAlgo: DeviceIdHashAlgorithms.MD5, separatorChar: ":", separatorEveryChars: 4)

to output:

5C7D:0C90:CF9E:0CE5:6095:6179:E8E8:2E7D

HashAlgorithms.None (plain)
HashAlgorithms.MD5
HashAlgorithms.SHA1
HashAlgorithms.SHA256

would be more practical in usage.

DeviceIdBuilder hangs due to Windows AddSystemSerialDriveNumber() call when using DeviceId.Windows.Mmi

I updated my nuget package reference(s)to 6.0.0 today and used your new syntax for various platforms. I experienced consistent hanging when adding in the drive serial number AddSystemSerialDriveNumber() for Windows:

var deviceId = new DeviceIdBuilder()
		.AddMachineName()
		.OnWindows(windows => windows
			.AddProcessorId()
			.AddMotherboardSerialNumber()
			.AddSystemSerialDriveNumber())
		.ToString();

Package references:

<PackageReference Include="DeviceId.Mac" Version="6.0.0" />
<PackageReference Include="DeviceId.Windows" Version="6.0.0" />
<PackageReference Include="DeviceId.Windows.Mmi" Version="6.0.0" />

The hang goes away when I use the WMI package instead <PackageReference Include="DeviceId.Windows.Wmi" Version="6.0.0" />. Alternatively, I can keep the MMI package and remove the call to AddSystemSerialDriveNumber().

Might I also ask why the language changed for the the method AddSystemSerialDriveNumber()? It used to be AddSystemDriveSerialNumber() like the other platforms. Lastly, thank you for the excellent work that went into this library.

Error: Could not load file or assembly Microsoft.Management.Infrastructure

Is it a bug or am I doing something wrong? Appreciate any help.
